A knowlege of the physical and thermal properties of grains is essential in the design of machines and structures for production, handling, and processing agricultural products. The absolute magnitudes of the physical properties of grains must be evaluated as a function of moisture content.For the point of view, this investigation was carried out to obtain some basic data for physical properties of grains; rough rice, milo, and yellow dent corn.Experiments were taken for size and shape factor, density, coefficient of friction, and thermal conductivity with different moisture content of the grains. These results were discussed by reference of published data.The results obtained are summarized as follows: Each physical prorerties, except size and shape factor, were influenced significantly by the moisture content of the grains, and expressed with the linear function. Therefore, regression analysis was applied to all data to determine the effect of moisture content on the physical properties. The regression equations determined for predicting physical properties were presented in part IV.
